Application led March 19, 1923. Serial No.1 625,961.

This invention relates to a soclet member ysuch as the well known socket wrench or key and j iarrticularly to a cleaning and eject ing device. therefor. lWhen such socket wrenches are used to remove a nut, the nut oitten sticks in the socket owing to the fact that said nut is often burred or damaged and trouble and inconvenience are often eX- perienced in removing said nut, which operation usually takes considerable time. Such socket wrenches also tend to accumulate dirt, grease, etc., inthe socket, which often becomes hard and interferes with the quick application and useot the wrench.

lit is an object of this invention therefore, to provide a socket wrench having` simple and edicient means for cleaning the same and ejecting a nut therefrom.

It is a 'furthe-r object of the invention to provide such a cleaning means comprising a plurality oit spaced prongs movable longitudinally in the socket and preferably tting close against the sides of the socket walls.

It is a further object ot the invention to provide a socket wrench having a shank eX- tcnding from one end on which slides a sleeve carrving the prongs which are movaole in the socket, said shank also preferably being provided with means limiting the movement ot said sleeve.

These and other objects and advantages of the invention will more Jfully appear from the following description made in connection with the accompanying drawings, in which like reference characters refer to the same parts throughout the didier-ent views, and in which7 Fig. l is a view in elevation of the device, a small portion thereof being shown in section;

Fig. 3 is avertical section taken on line 3 3 of Fig. l as indicated by the arrows;

' a horizontal. section taken on linev 7 7 of Fig. 6 as indicated by the arrows; and

Fig. 8 is a vertical section taken on the line 8-8 of Fig. 3.

Referring to the drawings. the dcvicecoinprises a member or head l illustrated as of substantially cylindrical 'forinhaving therein an angular `socket 2 opening at one end thereof. rlhe member l is substantially closed its other end and has projecting therefrom a shank 3 illustratedas oi. cylindrical forno9 which shank is of smaller diameter than the socket I2. A shoulder is thus formed between the'meniber 3 and one end oi the head l and said head has a plurality ot openings extending' through this shoulder' into the socket 2. The shank 3 has a sleeve l fitting and slidable thereon, from one end of which project a plurality of narrow prongs 5. These prongs 5 project into the openingsin said shoulder and thus extend. into the socket 2 and in the embodiment of the invention illust-rated, said prongs are shown as of substantially triw angular shape in cross section and having their outer sides fitting the angles formed by said socket walls and disposed closely adjacent said walls. The movement of the sleeve-1l away from the head l is limited by any suitable means secured to the shank l, such as the illustrated screw 6 threaded into said shank. The shank is provided at its end remote from thehead l with a squared or angular portion 7 affording means for turninge,` said head 1 by the application of a suitable wrench.

In operation, the device will be placed in position with the socket 2 fitting over a nut and the wrench turned to remove the nut. After the nut is removed, the saine can be quickly ejected by sliding the sleeve i longitudinally of the shank 3, it being understood, of course, that said sleeve and prongs 5 are withdrawn during the removal of the nut. rThe sleeve 4C and prongs 5 can also be reciproca-ted to clean out and eject any dirt, grease, etc., which has lodged in the socket It desired, more than two of the prongs 5 can be provided and in the niodiiication shown in Figs. 5 and 7, the' sleeve 8 which similaigto and a counterpart of the sleeve Ll is providedjwith six prongs 9 similar' toV the' prongs 52 which pron 9 are shaped to tit in Vber of nuts.

the angles of the socket. lVith such a device, all of the dirt Which might collect in the socket and the angles thereof will be quickly ejected therefrom and a nut can also be quickly and easily ejected from the socket.

.From the above description, it is seen that applicant has provided an extremely simple and eicient means for cleaning a socket wrench and ejecting a nut therefrom. By having the prongs oppositely arranged, the pressure is evenly distributed on the nut so that there is no tendency for the same to bind in the socket as would be the case if the nut were engaged only at one edge. The sleeve il slides easily on the shank 8 and it will be noted that the dimensions of the Wrench are not increased by the cleaning and ejecting means, so that the Wrench can be used in the small spaces. The cleaning and ejecting means thus do not interfere in any Way with the use of the Wrench. 1t will be noted that more than one nut can be removec before the nuts are ejected from the socket, the ejecting means insuring that said nuts will not becomev fastened in the socket. Time is thus saved in removing a large nuni- If the head l should be twisted olf of the shank 8, the sleeve 4 and prongs 7 can readily be reset or applied to a new shank. The device is easily made and assembled and can be produced at small expense.

It will, of course, be understood that various changes may be made in the form, details and arrangement and proportions of the parts wit-hout departing from the scope of applicants invention, which generally stated consists in the manner shown and described and set forth in the appended claims.

lVhat is claimed is:

l. A socket wrench comprising a head having an angular socket therein opening at one end thereof, a shank extending longitudinally from the other end of said head and of smaller diameter than the diameter of said socket thus forming a shoulder against said head, said head having a plural ity of openings extending through said shoulder longitudinally of said head, a sleeve slidable on sai-d shank and carrying a plurality of prongs slidable through said openings to engage a nut held in said socket for ejection.

2. A socket wrench comprising a head having an angular socket therein opening at one end thereof, a shank extending longitudinally from the other end of said head and of smaller diameter than the diameter of said socket thus forming a shoulder against said head, said head having a plurality of openings extending through said shoulder longitudinally of said head, a sleeve slidable on said shank and carrying a plurality of prongs slidable through said openings to eugage for ejection a nut held in said socket, said prongs being arranged in pairs at diametrically opposite sides of said socket to exert equal pressure at opposite sides of the nut.

A socket Wrench comprising a head ha ving an angular sockettherein opening' at one end thereof, a shank integral with and extei'iding longitudinally from the other end of said head and of smaller diameter than the diameter of said socket, thus formino' a shoulder against said head, said head having a plurality of openings extending through said shoulder longitudinally of said head, a sleeve slidable on said shank and carrying a plurality of nai-rouT prongs substantially triangular in cross section slidable through said openings and fitting in the angles formed by the Walls of said socket, said prongs being arranged in pairs at opposite sides of said socket, and means on said shank limiting the outward movement of said sleeve and prongs, said prongs being adapted to clean the socket and eject a nut therefrom In testimony whereof We alfix our signatures.
